Abstract
The invention relates to a forced feeding device for recycling and pelletizing of a plastic film. Two forced feeding devices with different rotary speeds are arranged on a hopper stirring shaft, the rotary speed of a stirring rod part is slower so as to mainly damage the bridging phenomenon of the plastic film, the rotary speed of the lower half part is faster, and a spiral screw at the front end presses a material into an extruder in a balanced way; and the packing density of the plastic film is changed, and the rotary speed and the constant torque can be automatically adjusted by a torque motor, so that a screw channel in the extruder is filled with the plastic film. The yield is improved, and the production is stabilized, and meanwhile, the cost is reduced, and the energy is saved.
Description
Affiliated technical field
The present invention relates to a kind of extruder and force charging mechanism, in reclaiming the plastic sheeting granulation, the mechanism that has automatic equalization in extruder, to feed in raw material.
Background technology
At present, in the plastic sheeting reclaiming industry, plastic sheeting reclaims and has a lot of problems; Because the plastic sheeting bulk density is lower, is about about 0.17g/cm3, plastic sheeting can not effectively get in the screw rod; Can not enrich screw channel; And in hopper, be easy to generate " bridge formation " phenomenon, cause output very low, granulation after the bulk density of existing method employing artificial pressure material mode or change plastic sheeting.The mode of hand stock is inadvisable, and reason is a job insecurity, and work under bad environment, danger.The bulk density mode of change plastic sheeting consumes energy bigger, needs improve cost recovery greatly to granulation again behind the plastic sheeting granule.
Summary of the invention
Easy in hopper in order to overcome plastic sheeting " bridge formation " and can not enrich the extruder screw screw channel, and the invention provides a kind of pressure feeding device, adopt a kind of two kinds of different rotating speeds pressure feeding devices that on a shaft, have simultaneously; In hopper in the past, adopt the method for shaft, destroy plastic sheeting " bridge formation ", screw screw rod binder is set preceding; But the method is having a lot of problems in experiment, as rotating speed soon can be too much in screw rod, be pressed into material, cause and extrude main over current of motor; And driving lever can drive plastic sheeting, stirs at a high speed at hopper, if the slow PR of rotating speed is lower; As to the stirring motor speed governing, then be difficult to be coupled to the best with the extrusion screw rod rotating speed, therefore design a kind of two kinds of different rotating speeds that on a shaft, have; And change stirring motor into torque motor, require first half puddler rotating speed slower, destroy plastic sheeting as long as reach " bridge formation " phenomenon; The bottom revolution speed of screw requires very fast; In extruder, be pressed into the plastic sheeting of compacting, guarantee that plastic sheeting is full of screw channel, and can be according to the counter firmly automatic permanent torsion output different rotating speed of size of doing. two kinds of rotating speed speed ratios are 3.
The technical solution adopted for the present invention to solve the technical problems is
Needing that worm gear is subtracted machine output collar bush improves; Output collar bush lengthening, the front end lengthening connects with the stirring cover, and the rotating speed of output is the specified output speed of reductor; End flanges is installed the self-control small box behind reductor; Collar bush rear end elongated portion connects with the interior gear wheel of self-control branch mailbox, after idler gear raising speed and transition, and the center and the collar bush centres of axle.Intracardiac binder screw rod is exported high rotational speed in the middle of collar bush in same; And be processed into spiral at axle head, and thereby be implemented in two kinds of output speeds being arranged on the axle, first half rotating speed is slower; The Lower Half output speed is very fast; And subtract at worm gear and to join torque motor on the machine, can be according to the size of anticaustic power, the purpose of automatic permanent torque adjustment output different rotating speeds.
The invention has the beneficial effects as follows
Realized on same axle center through improvement, exported two different rotating speeds, the slow main realization destruction plastic sheeting of first half rotating speed " bridge formation " phenomenon; The Lower Half output speed is very fast, and can change the bulk density of plastic sheeting according to the automatic adjusting output speed of the big or small permanent moment of torsion of reaction force; Make in the extruder inner screw screw channel and be full of; Improve output and steady production, fall cost simultaneously, energy savings.Realized at plastic sheeting granulation needs.
